' To all whom it may cfm/:em:A

Be it known that I, BERTRAND KEN- YQN, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful qimprovements m .Card-Index Drawers; and l do hereby.de .clare the following to bc a full, clear, and

enact description oi the invention, such as will enable Others skilled in the art to which it appertains to make and use the same. f

" My invention relates to improvements lp.

"card index drawers, and' more articularly to the means for operating the Ocking rod for securing the cards within the drawer, and its object is to provide means for Inovinor the rod vertically to and from a position be Ow the plane of the upper surface'o the bottom of the drawer to a position within the upper part oi the opening in the cards, said movement being vertical and edgewise, and then turning the rod to a horifaontal position within the openings to secure the cards in place, and in various features of construction and arrangement, as will more fully ape pear by reference to the accompanying drawings, in which:

Figure 1. is a plan view oi` a card index drawer with my device therein; Fig. 2. an enlarged detail in elevation of the mechanism at the front end of the rod with. the rod in elevated position; Fig. 3. the same of the mechanism at the rear end of the rod; Fig. 4. the saine as Fig. 2. with the rod in lowered position; Fig. 5. the same as in Fig. 3. with the rod i lowered;v Fig. 6.a detail oi the rod operating vmechanism shown in elevation from the direction opposite Figs. 2 and 4; and, Fig. 7. a

- vertical section of the same ina plane at right 'angles to Fig. 6.

Like numbers refer to like parts in all of the figures.

# l--l represents bottom plates *of the tween which are rods 2 and 3 within the ed" es thereof.

" as a rock shaft as hereafter described. Mid- V.way between these rods and centrallyet the .drawer is a la't locking bar having a journal l 7' at each `end midway ot its edges.

rto the respective ends of the drawer are Secured plates 'fand 6 each provided with a vertical slot 'l5 in which the journas. 7 are vertically movable and rotative. To raise and lower the journals in the slots in the plates 5 and 6, one oi the round rods (3 in this case) is made rotative thus forming-a rock-shaft to the respective ends of which are rigidly attached arms 8 and 9 having slotted openings 1n their movable ends in which are inserted the journals 7 on the ends of the locking bar 4. The rock-shaft thus serves to connect these arms and move the same simultaneouslyT to raise and lower the locking bar 4. To accomplish this movement, I provide a handle 'having a shank 19 extending' through the front ot the drawer and rotative therein on the inner end of which is mounted a crank wheel 16 having a crank pin 17 on which pin is journaled a connecting rod 18 extending downward and connected to the end of the journal 7 of the locking bar 4. B rotating this handle, the end of the bar 4 wil be raised and lowered and the arms will be ymoved simultaneously and thus carry the locking rod u and down in the slots 15.

`To iInit the rotation of the crank wheel 16 to the upper and lower'positions of this har,

the connecting rod 18 is oil-set laterally from the crank-pin, one-half the diameter of the shank 19 and engages the same at the upper and lower dead centeroic the movement of the crank pin, thus 'limiting the in ovement of this wheel 16 to one-half revolution.

scends, a forkedor toothed member 12 is' rigidly secured to the inn/er end of the shank 19 and engages a substantially similar mein ber 13 rigidly secured to the locking bar 4 and in the same plane. Thus as the bar rises during the last portion of its movement, thesemeinbers 12 and 1.3 en age in a manner analogous to gear teeth an turn thel oar 4 one-fourth of a revolution u on its journals and remain interlocked to ho d the bar from turning in' either direction as shown in Fig. 2. To guide the bar 4 in vertical position a it rises and falls in the slotsa vertical guide 14 extends alongside 'of the slot 15 in the plate 6 and slidablylengages the -Jiat side @il the `locking bar andA thus pr'events it from turning upon its' axis during Aits vertical movement in the slots. A

in operation, by turning the shank 19 oneiheli revolution, the rod is carried-npA werel'reni below the plane Oi; the upper sur- To l turn the locking bar 4 from vertical to hori- IOO lse

face of the bottom to proper locking osition i within a keyhole slot in the car s, (not shown) and then turned to horizontal position and held from further movement, thus 5* securely locking the cards in the drawer. A reverse one-half revolutionof the shank 19, turns the locking bar to vertical position and then carries it downward vertically and -edgewise to below the plane of the upper sur- 0 face of the bottom. When in this position, the bar is wholly beneath the plane of the cards, and cards having no openings therein, can be used in the drawer, if so. desired.

It will be noted that the rod moves vertically and edgewise until it has reached its upper position. It may thus be used with cards having very narrow keyhole slots in 'their lower edge to receive the same, thus using but little of the card surface to form the slot.

What I claim is:

.1. In a card index drawer, a rock shaft, parallel arms rigidly attached to the rockshaft, a flat locking bar journaled in the arms 5 and carried thereby, means for raising and4 lowering the arms, and means for rotating and holding the bar.

2. In a card index drawer, vertically slotted plates, a flat locking bar having journals on its ends traversing the slots and rotative therein, a rock-shaft, parallel arms rigidly attached to the rock-shaft and having slots to receive the journals of the bar, means for raising and lowering the arms and means for turning and holding the bar.

3. In a card index drawer, a rock-shaft, parallel arms rigidly attached to the rockshaft, a manually rotated crank wheel, a rod connected to the lwheel and to one of the arms, and a locking rod supported and adf justed by the arms.
